What does the DRM on the inside of a German Beer Stein Lid?

Answer 1

The DRM (Deutsches Reinheitsgebot Mark) on the inside of a German beer stein lid signifies adherence to the German Beer Purity Law, which dates back to 1516. This mark ensures that the beer produced complies with the standards of using only water, barley, and hops, maintaining traditional brewing practices. It serves as a quality assurance symbol for consumers, reflecting the authenticity and craftsmanship of the beer contained within the stein.
